SAFETY-LOCK- To all whom it may concern: 5

Be it known that we, PIERRE L'IEVENS, a

subject of the Belgian King, and GUILLAUME JAHN, a subject of the GermanEmperor, residingat Brussels, Belgium, have invented new and usefulImprovements in Safety- Locks; and we do hereby declare the following tobe a full, clear, and exact description of the same.

nation-locks for V&l1SBS,'bOX6S, trunks, and the like, and has for itsobject the provision of a lock of this character wherein the lockingmechanism is opened by a prescribed movement of a plurality ofcombination members wherein the lock may be retained in an open positionby said members, and, further, wherein the parts may be so adjusted asto permit the owner of the valise or trunk to readilychange thecombination.

The invention will be more particularly described in connection with theaccompanying drawings and will be more fully ascertained "of Fig. 3.

' 5 of Fig. 3. Fig. 6 is a similar View showing the parts in a differentposition. Fig. 7 is a detail bottom view of one of the combinationmembers, taken on line 7 7 of Fig. 8. Fig. 8 is a side elevation ofoneof the combination members and the locking-nut therefor. Fig 9 is alan view of one of the locking-disks embodied in the operativestructure. Figs. 10 and 11 are detail plan views, respectively, ofoperative parts of the lock.

Like characters of reference designate similar parts throughout thedifferent figures of the drawings. I

As shown, the invention comprises the lock proper, which is indicated asa whole by A and is mounted upon the frame A of the valise, and thelock-engaging member, which is indicated by B and is mounted upon theframe B.

Referring to the structure of the body of the'lock, the same comprises astationary casing 1, whose top wall is slotted at 2 and provided withlooking projections 3, which form one of the elements of the lock properSpecification of Letters Patent. Application filed July 29,1905. SerialNo. 271,833.

and will hereinafter be referred to as the stationary plate.

4 designates a disk-plate mounted upon the stationary plate 1 andprovided with slots 5, terminating in enlargements 6. The slots 5 areadapted to fit over and operatively engage the projections 3, whichlatter limit the movement of the disk-plate 4' in It will also beobvious that the slots of the plates 1 and 4 are approximately of thesame when in the position shown in Fig. 3. A plurality of locking-disks8, equal in number to the slots provided in plates 1 and'4, are mountedupon the latter and are provided with cylindrical shanks 7, whichproject through the enlargement 6 of plate 4 and also *through slots 2of plate 1, the contracted slots 5 of plate 4 retaining-said shanks anddisks in prescribed relation with the plate 4, but permitting rotarymotion of the disk.

length and that they are adapted to register Said locking-disks areprovided with lockin recesses 9, which preferably diverge from theirbases outwardly, the base portions of said recesses being equal in widthto the projections 3 and adapted to cooperate therewith in certainadjustments. One of said disks 8, preferably the center one, is providedwith a concentric slot 22, registering with the base portion of itsrecess 9.

A plurality of combination members 'in the form of centrally-recessedknobs14 are provided, adapted to ijnclose the disks8 and the projections3 and to extend downwardly toward the plate 4. Said combination membersare provided on their upper faces 'with a plurality of numerals orSymbols or like designating-marks and with depending shanks 13 of polyonal cross-section, being reduced cylindrica 1y at 13 and having afurther threaded reduction at 15, adapted to be engaged by nuts 16; Theshanks7 of the disks 8 are hollow and are complemental in formation withthe shanks 13 to provide nonrotative engagement between the 'lo'c'kingmembers l4'and the disks 8. The which is indicated as a whole by A, ispro--v vided with slots 17*, through which the cyplate 17 lindricalportions 13* project, said slots 17 providing for movement of the shanks13, looking members 14, and disks 8 in one direction. The nuts 16 enga ethe lower face of the plate 17 and hold the ocking members 14,,

and therethrough the disks 8 and plate 4, in

position upon the plate 1. It will 'beobvious.

from the foregoing that the nuts 16 may be removed, thereby permittingdisconnection of the locking members 14 from the disks 8 andreadjustment of said members with respect to the disks 8 whenever it isdesired to change the combination.

Below the plate 1 there is provided a locking-plate 10, through whichthe hollow shanks 7 project, said plate being yieldingly held inposition by a spring 11, resting upon Washers 12, secured to shanks 7.Said locking-plate is provided with locking projections 19', as shown.in Figs. 3 and 4, adapted for en gagement with catches mounted upon aplate 20, constituting the lock-engaging member and secured to framemember B. Said catches project into the casing 1 through slots 21,formed therein, in a manner to be engaged by said projections 19. Thelocking-plate 10 is normally held in a locking or extreme right positionby a spring 18, secured to lugs upon the plates 10 and 1, respectively.

The operation is as follows: The parts in their normal position, asshown in Fig. 3 and as held'by spring 18, provide for a clearancebetween the projections 3 and recesses 9 of the disks 8, therebypermitting the latter to be freely turned through the locking members14. Assuming that the parts are in the osition shown in Fig. 3 and it isdesired to ock the valise, the frames A and B are operated together,thereby engaging the catches of plate 20 with projections 19, therebeing a sufiicient clearance between the projections 3 and theperipheries of the disks 8 to permit rotation of the latter. After theframes A and B" have been secured together, as described, thecombination is fixed by turning the locking members 14 to bring therecess 9 out of register with the projections 3, this operationpreventing movement of the plate 10 to the left a sufficient distance todisengage the projections 19 with the catches of the plate 20. In orderto position the locking members14 in a manner to unlock the valise, itwill be necessary to turn the locking members 14 to bring each of theminto a registering position with the projections 3, and to do this thecombination must be known to the operator. Assuming that the operatordesires to unlock the valise, he will rotate the locking members 14 in amanner to bring the recesses 9 into register with the projections 3, andwill thereupon move the parts to the left, thereby disengaging theprojections 19 from the catches of the plate 20. If it is desired toretain the parts in position to prevent the spring 18 from bringing theprojections 19 into engagement with the catches of the plate 20, theparts are moved to the left in the direction of the arrow shown in Fig.6 until the bases of the recesses 9 are in engagement withtheprojections 3, whereupon the central locking member 14 is rotated toengage the central projection 3 with the concentric slot 22, therebyholding the movable parts in an extreme left or unlocking position. Ifat any time it is desired to change the combination, any one or all ofthe locking members 14 may be disengaged from the disks 4 by firstremovin the nut 16 and replaced in a manner to change the relation ofthe recesses 9 With respect to the combination members upon the lockingmembers 14.
